Be it known that I, JOHN'PIDNKA, 're'sid-L ing at Woodlawn, in the county of Beaver and State of Pennsylvania, citizen of the I '5 Republic of Poland, have invented or discovered certain new and 'usciul' Improve-- for Sheet Material, of which improvements the following is a speci- Editions.

My invention relates to limprovementsinlconveyers, and finds particular application chine of ajtin-plate mill,

. carry the plates one by one from the bran-- ning machine and to stack them- -antomatiically upon buggies. Hitherto it has been necessary tozgather'by hand the plates as they lie superposed in irregular manner on the delivery s de of the branning machine. An attendant gras'psbyopposite edges a handful of the plates and turning them to vertical position and holding them loosely, he drops them on edge upon a suitable sur-v face, thus stacking them after the manner of a pack of cards. It is an undesirable ex-. pensmto .pa for aworlxman here; and, besides there isof necessity, incidental to an with plates falling one n'another in a 'haphazard manner, and

larly superposed plates, and to the: dragging about a very a reciable'element of damage. it is esirableif possible to prevent. A conveyer embo ying my invention is Fig. is aplan view from above; Fig. is a view in vertical section on the planeindicatedvby the line IL-II, Fig. I." Fig. III is a view; in, side elevation.

mulated that the attendant has to do, after the manner indicated above. It will be understood that the branning machine includesmetlhanism for effecting advance of plates under treatment through it, and that the delivery roller 2, and indeed, the conve er rollers 4511s well, constitute part of t at My invention is found in conveyer ap aratusarranged to receive the plates as t ey advance oneby one from rolls 4, and, receiving them, to convey them and stack them automatically in a buggy or on another suitable support. This conveying apparatus in-. cludes, combined with delivery mechanism such as that described or its equivalent a live transfertable and a bum r With these a chute or chutes wiliir be correlated in the manner shown; The livetable is made up of a plurality of parallel rollers 5, in this case seven, although the number is relatively unim ortant. It

spring. dinarily lies across the delivery end of t e conveyer made upof rollers-4. These rollers 5 lie perpendicularly to rollers-4 and in asome what lower plane. As conveyer elements,

theyhave by virtue of their position and their rotation two characteristics: They serve as skids upon which plates advancing from rollers 4 slide, until the previously ac quired momentum be expended; and they serve also to impel the lates in a new direc-,

ht angles to that imparted by the branningmachine and its immediately associated conveying mechanism.

Rollers 5. are, aswill be perceived, dgeared tofrotate in. unison, a connection ma through clutch mechanism 6 be establishe atwill with either onev end or the other of'the axle ofv the positively together,

driven proximate roll 4, and so rollers 5 may be rotated'to carry the material either to the right or to. the left, and in adirection at right angles to the direction ofadvance from the branning machine. At theopposite end of rollers 5, remote from rollers4, is-arranged a spring 7. This takes the formof a heavy leaf or ban ,bowed toward the advancing. plate, andanchored at its ends by being folded about the opposite margins of late lay and yet securing the spring from displacement opposite ends of transfer table 8, the fold being such as to If I made i, 1 9?

By'tliis'arrangemeet the whole maybe removed or purposes of re air melee give free and ready access to machine. In this "connection observed that the delivery roller 2"-is shown to be a permanent part of the branningmachine, and that it is provided with a 1' gear 14 which when the, carriage 13 is brought to place meshes with a gear 15 mounted on carriage 13, and through which the proximate roller 4; is driven. By these mstmnientalities, together with. the sprockets and v m ,the whole conveying apiven.

Operation is as follows. When .the brann ingma line is in service the mechanism foreflecting advance of plates through it is opei gtion and as part of that mechanism 118:2 is turning. Carriage 13 :being in pla e, he nsfer ee ns ing of will ers 4 is active and in' condition to carry indicated by the l Fi I.

substantial ,aceuraey, form element is really the of ppiqr difficulty in properly sta delivered plates.

,Considering the jndiyidual plate, it lies upon rollers 4 in an indeterminate and :uaually irgggulan position and in response to the turning of the live rollers 4 it advances over and we irom rollers 4. As itadvanees it comes to bearing upon rollers 5 and slides under the momentum which it Ifg the successively then possesses longitudinally upon rollers 5. The nferior position of rollers 5 facilitatos' such advance. The rotating rollers; 5 tend to turn the plate as it so slides, but this signifies not at all. The vaneing with such momentum strikes upon s 7. Spring '7 forms a. double functlgi l it rights the pl t el-in position, and it absorbs it throws the plate back upon rollers '5 in tan a ly qu es? 1 h th P a e has o il f w e 'iit lies upon rollers 5 fiee of the aligned-with the direetion of further travelf'orsubstantially so, and sub stantially centered in the path offifurther travel, and entirely passive -to the operation of rollers '5. hey alone are now effective.

V further advantage wi'll be peteeivedin arranging the transfer table omposed' of rollers 5, at lower level than that c" posed of rollers 4. (In the machine I have built and powhave' in operation the interval is two inches.) If on any account it be do sired, delivery may he'interru "for a iengv t s w t t m i s; sp m e the branning mael fie' 'Iihe hitherto aegis-ea p at it slides across the table for-med by rollers 5 and m enwntum,iend

The practlce of m invention saves time, for there is no use to stop the branning machine because ofconditions of delivery;

and, as I have already explained, the cost and wastage incident to manual dragging and stacking of the delivered plates are I avoided. T. 0

I claim as my invention: 1. Conveyer apparatus for sheet material including two-transfer tables, each consistin of: positively driven rollers, "the two ta les bein arranged angularly theone to the other, t e second table lying beyond and extendin across the deliveryv end of the first, an a spring arranged on the side of the second table remote from the delivery end of the first table whereby the advancing sheet rebounding from the spring lies upon the rollers of the second table squared to its new direction of travel substantially as described.

2. Conveyor apparatus for sheet material including two transfer tables, each consisti of positively driven rollers, the two tfifiles being arranged angularly the one-to the other, the second table arranged at a lower level than the first and lying beyond and extending across the delivery end of the first, its component rollers afiording a skidwa to material advancing from the first a strap spring arran d at the side 0 the second ta end of the first table and bowed towards the first table, substantially as described.

including two transfer tables, each consist- .ing of positively driven rollers, the two tables being arranged angularly the one to the other, the second table lying beyond and first, the ultimate roller of thefirst table adapted to intermesh alternately with one or the other of the two said beveled gears upon the ultimate roller of the first table, and means for shifting the said beveled gears of the second table, substantially as described.

including two transfer tables, each consistthe second table remote from the delivery le remote min the delivery Witnesses: I a

3. Conveyor apparatus for sheet material extending across" the delivery end of the being provided at its 0 posite ends with oppositely disposed beve ed gears and the train of rollers which constitutes the second table being provided with beveled; gears 4;. Conve'yer apparatus for sheet material in of positively driveni rollers, the two ta les being arranged angularly the one to the other, the second table lying beyond and extendingacross' the delivery end of the first, its component rollers affording a skidwa to'material advancin from the first an abutment arrange on the side of end of the first table and affording an increasing resistance to a sheet advanclng from the first table across the-second. a

In testimony whereof I have hereunto set myhand. i
